2 Claims. (Cl. 52-714) ABSTRACT OF THE DISCLOSURE A Wall tie for a brickveneer wall is preformed to the final shape required and comes providedwith an integral and properly positioned nail to eliminate the usual tiebending and separate nail locating and positioning.

Related application This application is a continuation-in-part ofapplication Ser. No. 407,189 entitled Prefabricated Wall Tie Assemblyfiled Oct. 28, 1964, which application is being abandoned upon thefiling of this application.

Background of the invention (1) Field of the invention-This invention isdirected to construction devices and more particularly to wall tieswhich are used to tie brick veneer walls to adjacent sheathing in newhomes, new industrial building constructions and the like.

(2) Description of the prior art.Heretofore, a series of time-consumingand expensive steps have been required for a brick mason to secure theconventional wall tie to the sheathing. Conventional wall ties areformed from fiat strips of sheet metal having holes, corrugations orsimilar structure which allows mortar to become embedded therein.Conventional ties have a hole punched in one end in which the mason isrequired to locate and then position the nail for hammering. The nail isstarted while being held and is then hammered into the sheathing. Aftersecuring the wall tie to the sheathing, the mason is required to place abend in the wall tie adjacent the nail and the remainder of the wall tieis bent down onto the brick surface where mortar is placed beneath andthereupon and allowed to harden.

The above-described conventional wall tie and this method of securingthe wall tie to the sheathing have a number of disadvantages. The nailhas to be found and picked up separately by the mason from a nail bag orthe like, located in the hole, positioned correctly and held duringstarting of the nail into the sheathing. Substantial time is required topick up the nail, assemble the nail and tie and position the nailcorrectly while holding both the nail and the tie. A possibility ofinjury to the mason is encountered in this hammering process since themasons fingers are near the nail head during hammering. The tie must bebent into place upon the brick after the nail has been hammered in placeand this also consumes time.

Considerable improvement upon the conventional brick tie is provided bythe tie disclosed in Patent 2,262,130. The brick tie of this patentprovides a preassembled wall tie with an associated nail. The nail isplaced through a provided hole during manufacture of the tie and walltie material is bent over the nail to hold it in place. The tie of thecited patent is somewhat helpful in lessening the possibility of injuryto the mason. However, it has been discovered through use that since thenail is assembled loose within the tie nail hole, the mason still has toboth position and hold the nail while starting it. Failure to hold thenail in the cited patent tie assembly often- 3,389,525 Patented June 25,1968 times causes the nail to become bent and not usable. In the citedpatented tie a bending process is also still necessary after the walltie has been secured to the sheathing. Another disadvantage resides inthe fact that hammering must inherently be applied to the surface of abent metal portion instead of to the nail head where hammer blows aremore effective.

Summary of the invention According to the invention a wall tie ispreformed to the final shape required for joining a mortar joint to thesheathing and which eliminates the need for on-the-job bending asrequired in all prior art wall ties. The wall tie of the invention whenpreformed is also punched to receive a double-headed nail such that whenthe nail is cold-set it becomes rigidly and integrally fixed to theupturned end portion of the tie in a correct position for nailing andwith the nail head exposed for direct application of hammer blows.

The primary object of this invention is to provide a prefabricated brickveneer wall tie unit which includes an integral nail that is properlypositioned and positioned such that its head can be struck directly bythe hammer.

An object is also to provide a prefabricated brick veneer wall tie unitwhich is shaped during manufacture to the shape required forinstallation so as to eliminate any need for bending the tie on the job.

An object is also to provide a prefabricated brick veneer wall tie unitwhich requires less material to construct thereby establishing a lessexpensive wall tie.

Another object is to provide a prefabricated wall tie unit which isextremely simple in construction, strong, durable, reliable andefficient in use, and which may be formed from sheet metal and nail rodstock.

A further object is to provide a prefabricated brick veneer Wall tieunit which is so designed that the mason does not have to hold the nailand thus has a minimum of exposure to injury while securing the tie unitto the wall.

Description ofthe preferred embodiment Referring to the drawings indetail, a prefabricated brick veneer wall tie unit20 is shown in itspreferred embodiment. Wall tie 20 is shown being formed of a rectangularshaped, bendable metal strip 21 of a suitable gauge metal, for example,a .026 gauge metal. The base 25 of strip 21 is formed to a predeterminedlength L equal, by conventional masonry practice, to the length S of thespace between the sheathing 31 and a point about onehalf inch in fromthe outside face of the brickwork. Wall tie unit 20 is so designed tofunction as a means of joining sheathing 31 and a brick veneer wallconstruction 22.

The metal strip forming the tie of the invention is bent duringmanufacture at a right angle to form the nail support and hammering endmember 24. End member 24 in turn is punched to provide a hole 26 and adoubleheaded nail member 27 is thereafter forced through hole 26 so asto reside in end member 24- as best seen in FIGURE 7 and with head 23 ofnail 27 flush with the inner face 2/ of the end member 24. Nail 27 ismachine-formed from nail wire and is then assembled with the separatelymachinestamped, bent and punched strip 21 to form the composite wall tieunit 20. It has been found particularly desirable to form nail 27 withboth a hammering head 28 and a second head or flange 30. The spacing Ybetween the two heads receives the flange 32. During fabrication thenail 27 is forced into hole 26 in a snug fit and in an immediatelyfollowing operation the flange 32 is pressed or cold-set so as torigidly secure nail 27 to the end member 24 and maintain it in a correctposition for hammering.

The base portion 25 is illustrated in the drawings as having holes 33stamped along its length. Holes 33 are effective as a means forembedding the tie it] in the mortor and providing support against strainbetween the veneer wall 22 and the sheathing 31. Substantial anchoragein the mortar is desired to avoid the Withdrawal of the tie 20 onceembedded therein. Other configurations may be employed, e.g., grooves,slots or corrugations, and punched or formed in the base member 25.

Referring to FIGURES 8 and 9, tie unit 20 may be used in connection withwood sheathing 31 and brick veneer wall 22. The bricks are set by mortarin the usual well-known manner, and the veneer wall 22 and sheathing 31are joined by the prefabricated wall tie units 29 constructed inaccordance with the invention. The installation, positoning andfastening of the prefabricated brick veneer wall tie units of theinvention can be executed rapidly and with limited possibility of injuryto a workman. As best seen in FEGURE 8, the workman can hold the tieunit by the base 25 and does not have to hold or position the nail nordoes he have to assemble the nail and tie. The workman only has to pickup a single unit which comprises the entire tie and can hold the end ofthe tie far removed from the nail head and yet apply blows directly tothe nail head 28 during hamming as illustrated by the hammer 35. Duringhammering, the workman knows the nail will be steady and will hold acorrect position since the nail is integral with the tie.

From the foregoing description, it will be observed that I have deviseda simple and inexpensive prefabricated wall tie unit that can be used inconnection with almost any type of brick veneer wall. While a specificembodiment has been shown and described, it is obvious that the specifieform may vary without departing from the scope and spirit of theinvention.
